How to Protect a Coax Cable
- 1). Remove the coaxial cable from the back of each appliance you want to protect. Satellite boxes, cable Internet boxes, and television sets are all susceptible to power surge.
- 2). Screw the coaxial cable onto a coaxial cable surge protector. These surge protectors are made to stop current at the appliance. Surge protectors are made in two styles: a box style that requires you to ground the protector through a ground wire and a cylinder-type surge protector that works without the need for a ground.
- 3). Screw the surge protector into the appliance if you choose a cylindrical surge protector. Attach a length of coax cable from the surge protector to the appliance if you are using a rectangle-style surge protector.
- 4). Tape the connections with self-vulcanizing weatherproof tape for added protection. You may also wish to tape any outdoor connections with the tape to prevent the infiltration of moisture that can ruin coaxial cable. On outdoor connections, wrap the self-vulcanizing tape with a layer of electrical tape for stability.
